1 represents the main frame of the machine which may be of any suitableconstruction so as to support the working parts of the machine.

2, Figures 2, 7 9, and 18, represents a number of main dials whichregister the total of the numbers which are added together. These dialsconsist preferably of cup-shaped wheels which are numbered on theirperipheries and are mounted in their proper order on a transverse dialshaft 3, which is journal'ed in bearings on the main frame, the dialsbeing so arranged that the dial representing the lowest number isarranged on the right hand end of the series and the dials representingthe successively higher numbers being arranged successively in theirorder toward the left from the dial representing the lowest number. Thelowest or right hand dial is preferably divided on its periphery intoone eighths so as to indicate fractions of a cent in III , wardly mas-meighths, and the remaining dials are graduated on their peripheryaccordin to the decimal system into tenths. As s own in the drawings tenof these dials are shown and extend from fractions of a cent to tens ofmillions, but if desired, additional dials may be added to the right andto the left of the series, if it is desired to register smallerdivisions of a cent or more than tens of millions. Each of the dials 2is provided on its lefthand side with a gear pinion 4, which is rigidlyconnected therewith, as shown in Figures 2, 7, 9, and 18.

The pinion of the fraction wheel has eight teeth while the inions of theremaining dials are each provi ed with ten teeth. 5 represents the mainregistering gear segments, one of which is provided for each of thedials 2 and is adapted to engage with the pin on thereof, for operatingthe respective dlal. Each of these gear segments is arranged in rear ofits companion gear pinion and is provided at its lower end with arearwardly projecting arm 6 which is pivoted loosely on a transversesupporting rod 7 This rod 18 mounted with its ends on the upper ends oftwo rock arms 8 which turn loosely with their lower ends on a transverserock-shaft 9. The rock-arms 8 are connected by a transverse bar 10 whichcompels the two arms to move back and forth together. In the normalposition of the gear segments when the machine is at rest these segmentsare retracted rearout of engagement from the dlal pinion of the dialsand the segments are elevated so that their lowermost teeth are oppositethe spaces between the ad'acent teeth of the dial pinions, these spacessing in line with the pivots of the piriions and the gear segments.

The gear segments are yieldingly held backwardly out o enq'agementwiththe dial pinions bymeans of springs 11 (Fig. 14) con? necting therock-arms 8 with a stationary part of the frame. Figure 14 shows one ofthe springs 11 connecting one of the roclr-arms 8 with a transversestationary bar 12 in the rear part ofithe machine. The gear segments aremoved forwardly so that thelr teeth engage with the dial pinion 4, bymeans of a shifting rock-arm 13, WhlCh is preferably secured to theright hand roclt-arm 8 and projects rearwardly. Upon raising theshiftlng rock-arm 13, the rock-arms 8 are swung forwardly and the gearsegments 5 are engaged with the dial pinions, whileupon swinging theshifting rock-arms downwardly, the rockarms 8 are swung rearwardly andthe gear segments are disengaged from the dial pinions.

14 represents a cam whereby the gear segments are engaged with the dialpinions. This cam is mounted on the upper portion of I a verticallyswinging rocking frame 15 which is arran ed on the right hand side ofthe machine. his cam is provided at its front end -with-an inclineorcamface16 and at its rear end with a concentric face .17. When the camis in its rearmost or retracted position, its

incline stands in rear of a rolleg or projection 18 on the rear end ofthe shifting arm 13, as shown in Figures'2, 7, 9, and 19. Upon swingingthe rocking frame 15, so that the cam 14 moves forwardly, the incline ofthe latter engages underneath the roller 18 and raises the arm 13,thereby moving the arms 8 forwardly. The throw of the incline 16 is justsuflicient to engage the teeth of the gear segments with the dialpinions. When the roller 18 has been raised to the top of the incline,the concentric portion of the cam engages with the roller during thecontinued forward movement of the cam and the latter does not shift thegear segments any further forward.

When the rear end of the concentric face 1'? of the cam passes forwardlyfrom underneath the roller 18, the constant pull of the springs 11causes the rock-arm 13 to be depressed and the rock-arms 8 to be movedrearward, thereby disengaging the gear segments from the dial pinions.Upon now moving the cam 14 backwardly together with the rocking frame15, this cam does not afiect the arm 13 and the parts connectedtherewith, but is affected by said arm at the last portion of thebackward movement of the cam, at which time the back or lower side ofincline 16 engages with the roller 18, which lifts said incline and atthe end of the backward movement of the cam, the latter clears saidroller and drops behind the same, as shown in Figure 2, preparatory toagain raising the roller 18 and connecting parts during the next forwardmovement of the cam 14.

For the purpose of permitting the front end of the cam to rise so as toclear the roller 18, this cam is pivoted at its rear end to the rearportion of the rocking frame 15. The upward and downward movement of thefront end of the cam is limited by means of a lug 19 projecting from theside of thecam and engaging with a slot in the adjacent part of therocking frame 15, as shown in Figures 19 and 36.

The rocking frame 15, is secured with its lower portion to a transverserock-shaft 2O journaled in the main frame and provided outside of theframe with a hand crank 21, as shown in Figure 19, whereby this shaft isrocked and the parts connected therewith are operated.

The gear segments 5 are raised to their highest position by means of areturn or lifting bar 22 which extends transversely underneath all ofthe arms 6 of the gear segments and which is connected loosely at itsrear ends with the transverserod 7 by lifting plates 23. 24 representstwo shifting arms which are mounted loosely at their rear ends on therock shaft 20 and which support at their other ends a transverse bar 25which transverse bar is connected at its ends, by two links 26, with thelifting plates 23, whereby upon raising the lifting arms 24, the liftingbar 22 is causedto IEJJSQ .he gear segments and the other partsconnected therewith resting on said bar. Upon depressing the transversebar 25, the lifting bar 22 is moved downwardly and the gear segmentsresting thereon are permitted to move downwardly with the bar until thesegments are arrested.

Eachof the gear segments is yieldingly held in contact with the liftingbar 22 by a spring 27 which connects the arm of the segment with thetransverse bar 25. If the downward movement of the gear segment isarrested while the whifting arms 24 continue to move downwardly, thelifting bar 22 is moved away from the underside of the arm of the gearsegment and the spring 27 is strained. The transverse bar 25 is arrangedat one end in a segmental notch 28 formed in the front part of therocking frame 15, as shown in Figures 2, 7, 9 and 19 and its oppositeend is arranged in a similar segmental notch 28, formed in a rockingframe 29 (Fig. 19) which is secured to the operating shaft 20 on theleft-hand side of the machine.

W'l1en the machine is at res; as shown in l 'igure 2, the transverse bar25 engages with the front side of the notches 28 in the rocking frames15 and 29. Upon turning the rocking shaft 20 forwardly by means of itshandle 21 in the direction of the arrow, Figure 2, the rocking framesare moved forwardly during the first part of the movement independent ofthe transverse bar 25. The latter remains at rest until the inclinedfront end 16 of the cam 14 has raised the arm 13 and moved the gearsegments into engagement with the dial pinions, during which movementthe rocking frames move idly to the extent of their notches 28 along theends of the bar 25 without disturbing the latter. After the gearsegments have been engaged with the dial pinions, the continued forwardmovement of the rocking frames causes the rear ends of their notches 28to engage with the bar 25 and depress the same, thereby causing thelifting bar 22 to be moved downwardly and strain the springs 27. Thiscauses all of the segments which are free, to be moved downwardly and tocontinue their downward movement until they are arrested. During thedownward movement of the gear segments, while they are in engagementwith the dial pinions, the latter and the dials connected therewith areturned in the direction of the ar row, Figure 7, until the downwardmovement of the segments is arrested. The extent which each dial isturned depends upon the position in which the downward movement of itsoperating segment is arrested. After the segments have been arrested intheir downward movement, they remain in this position while the rockingframes complete their forward movement. At the end of the forwardmovement of the rocking frames, the roller 18 of the rock arm 13 dropsoff from the rear end of the concentric part of the cam 14, therebyallowing the springs 11 to pull the gear seg-, ments rcarwardly out ofengagement with the dial pinions.

Upon now turning the rock-shaft 20 backwardly by means of the handle 21,the rock ing frames are moved backwardly until the front ends of thenotches engage with bar 25. When the latter is so engaged it is movedbackwardly with the rocking frames to the end of their rearward movementwhich causes the transverse bar 25 to lift the lifting bar 22 and thegear segments which have been depressed, into their highest or normalposition. During this upward movement of the depressed gear segmentsthey are out of engagement with the dial inions, whereb the dials arenot turned bacEwardly with the segments, but remain in their shiftedposition.

30 represents a number of elbow-shaped controlling arms. which form partof the devices whereby the downward movement of the registering gearsegments is controlled. One of these arms is arranged along the lefthandside of each gear segment and consists of an upright front part and ahorizontal lower part which extends rearwardly from the lower end of theupright part, thereby leaving a clear space in rear of the upright partof the controlling lever, as represented in Figures 1 2, 7, 9, 18, 30,42, 43, and 47. The rear part of the lower end of each controlling armis mounted loosely on a transverse supporting bar 31, while the upperend of its front or upright part is loose y connected with the upperportion of its companion gear segment. This loose connection permits thecontrolling arm and the gear segment to swing freely about theirindividual axes, which are arranged parallel but out of line, and alsopermits the gear segment to move forward and backward into and out ofengagement with its companion dial pinion. In the uppermost position ofthe controlling arms the same bear with their upper ends against atransverse stop bar 32, as shown in Figure 2, which limits the upwardmovement of these arms. Each controlling arm is provided on the rearpart of its upper end with a locking lug 33, and on the front part ofits upper end with a stop lug 34, both of which lugs project toward theleft and are preferably stamped out of one piece with the controllingarm.

The operation of the registering devices is controlled by a number ofelbow-shaped key levers which are arranged side by side and pivoted to atransverse supporting rod 35. Each key lever is provided with a loweraetuating arm 36 which projects forwardly and an upper stop arm 37 whichprojects upwardly along the left hand side of one of the controllingarms' and gear segments, as represented in Figures 2, 7, 1 8, and 42.Each of these key-levers is provided on the rear side I is moved forwardinto engagement with the adjacent dial inion, and the rocking frames areturned orwardly for depressing 5 9 ing the segment. At the end of thisforward the gear segment, the spring 27 of this segment will be strainedwithout, however, shi

movement of the rocking segments, the roller 18 of the rock arm 13 dropsoff from the rear end of the cam 14 the gear segment is moved rearwardlyout of engagement from the dial pinion and then the rocking frames move.backwardly without having shifted the dial.

The upper arm of each key lever is provided on its front side with avertical series of differential sto shoulders 39, which are arrangedstep'fas ion and extend from the upper end of this arm downwardly andforwardly thereon, or in other words the stop shoulders are arrangedradially out of line with one another and different distances from thepivot of the key lever. These stop shoulders of the key lever'areadapted tobe moved forwardly into the path of the stop lug 34, on thecontrolling 'arm. The stop shoulders are arranged different distancesfrom the stop lug 34, of the controlling arm, so that by movingdifferent stop shoulders of the key lever into the ath of thestop lug ofthe controlling arm, t e latter and the gear segment connected therewithmay be arrested at different points in their downward movement. Theuppermost stop shoulder of the key lever is most remote from thestop lugof the controlling arm and therefore requires the greatest forwardmovement of the key lever, in order to bring this stop shoulder into thepath ofthis stop lug.

The stop shoulders of the key lever are so arranged that the distancefrom the stop shoulders to the path of the stop lug 34 gradually growsless from the uppermost stop shoulder to the lowermost stop shoulder.The

relative position of the diiferentstop shoul-' ders of the key lever issuch that when its locking shoulder 38, remains in engagement with thelocking lug 33, and the gear segment is simply moved into and out ofengagement with its dial pinion, the latter remains at zero, if the samehas not been previously moved. But when the key lever has beenmovedforwardly, so as to disengage its locking shoulder from the locking lugand moves one of its stop shoulders into thepath of the stop In of thecontrolling arm, the latter arm and gear segment connected therewithwill be moved ownwardly, upon moving the rockmg frames forwardly, untilthe stop lug of the controlling arm strikes. the respective stopshoulder of the key lever which stands in 1ts path, as represented in Fire 7 whereby the ear segment while turning in engagement with theadjacent dial gear pinion, turns the same forward. By turning the keylever forward more or less and moving one or the other of its stopshoulders into the path of the stop lu 34, of the controlling arm, thedistance whic this arms descends can be varied, thereby varying thenumber of spaces which its gear segment turns the adjacent dial.

Main ml/mber key nwchaniem 40 represents the main keys whereby the keylevers of the main registering and recordin mechanism are operated, andwhich are guided with their depending stems in the top 41 and bottom 42of the key-board. As shown in the drawings, nine longitudinal columns ofthese ke s are arranged transversely side by side. T e first column onthe right hand side of the machine contains seven keys and representsfractions of one-eighth of a cent, the next column toward the leftcontains nine ke s andrepresents cents and, the remaining co umns ofkeys toward the left each contains nine keys and representsprogressively higher orders of numbers according to the decimal system,so that the registering keys in the last or left hand column representhundreds of thousands of dollars.

The lowest numbers of the several columns of keys are arrangedtransversely in a row on the rear part of the key-board and thecorresponding higher numbers of the several columns are arrangedlikewise in transverse rows and progressively in their order toward thefront end of the key-board.

Each of the registering keys is yieldingly held in an elevated positionby a spring 43 (Figs. 25 and 27) surrounding the stem of the key andconnected at its upper end to the key and bearing with its lower endagainst the bottom of the key-board. The upper movement of each-key islimited by a shoulder 44 formed on the upper part of its stem andengaging with the underside of the top of the key-board, as representedin Figures 25, 27, 38, and 39;

The downward movement of all of the keys is substantially the same, butthe arrangement of each column of keys lengthwise of the lower actuatingarm of each key lever causes the keys to bear against the lever atdifferent distances from its pivot so that by depressing different keysthe same distance, the key lever will be turned different angulardistances. The keys having the lowest numbers bear against theirrespective key levers nearest the pivot and consequently the levers arethereby thrown the greatest distance, and the uppermost stop shouldersare shifted into the path of the stop lug 34, of the respectivecontrolling arms. The throw of each key lever upon depressing any one ofits keys is so adjusted, that the proper stop shoulder on its upper armis moved into the path of the stop lug 34, of the controlling arm andthe downward movement of the respective gearsegment is arrested afterhaving turned the adjacent dial gear pinion a number of spacescorresponding to the number of the key which is depressed.

Loose connection for segments The loose connection between eachcontrolling arm and its gear segment, heretofore referred to, is shownin its simplest form in the connection between the controlling arm andthe gear segment, which are controlled by the initial or lowest columnof registering keys. As shown in Figures 1, 18, 30 and 43, the looseconnection between the controlling arm and the gear segment of thelowest registering device consists of upper and lower guide lugs 45 and46 arranged on the upper end of the segment and bearing a 'ainst theupper and lower guide faces 47 and 8, which are formed on the upper endof its companion controlling arm. As the controlling arm and segmentrise and fall, the guide lugs of the segment slide back and forth on theguide faces of the arm. The guide faces are so constructed that the backand forth movement of the segment on the arm is radial with reference tothe dial pinion in all positions of the segment. By. so forming theguide faces of the arm, the gear segment can be engaged with and'disengaged from the dial pinion in all positions of the segment withoutdisturbing the position of the dial pinion. The construction of theloose connections between the controlling arms and gear segments of allof the higher registering devices above the fractional registeringdevice, except the highest device are combined with carrying devices,whereby each registering dial, upon making one complete turn, causes thenext higher dial to be turned forward one space, thereby carrying up anumber from one order to the next higher order. The loose connectionsbetween the controlling arms and the segments and the carrying mechanismof the higher registering devices are constructed as follows As shown inFigures 1, 2, 7, 18 and 43, each controlling arm is provided at itsupper end with upper and lower guide faces 47 and 48 and its lower guideface is engaged by a lower guide lug 46 on the adjacent gear segment,the same as in the coupling between the controlling arm and segment ofthe initial registering device. The gear segments of the higherregistering devices are each provided with an upper guide lug 49 whichis adapted at timesto bear against the upper guide face 47 of thecompanion controlling arm in substantially the same manner in which theupper guide lug 45 of the fractional gear segment bears against itscompanion arm, the only difference being that the upper guide lug 49 ofthe higher gear segments are held out of engagement and separated by aspace from the upper guide face of the companion arm when no number iscarried from a lower to a. higher registering device. The upper guidelug 49 is held in this elevated position above the adj acent guide faceby a rocking latch 50 which is arranged in a notch in the rear side ofthe gear segment and which normally projects toward the left and engageswith the upper guide face 47 of the adjacent controlling arm, as shownin Figures 2, 30 and 43.

During the ordinary up and down movement of each higher controlling armand gear segment, the. latter is guided by its lower guide lug 46 andthe locking latch 50 engaging with the lower and upper faces of theadjacent arm, this movement being the same as the movement of thecontrolling arm and gear segment of the fractional registering device.Normally the downward movement of the controlling arm is determined bythe position of its companion key lever and this arm in turn controlsthe extent of the downward movement of the gear segment. When, however,the locking finger 50 is withdrawn out of engagement from the upperguide face 47 of the arm, the companion gear segment is capable ofmoving downward independently of the arm until the upper guide lug 49engages with the upper guide face of the arm. The extent of thisindependent movement of the gear segment with reference to its companionarm is equal to one tooth or space of the segment, so that by this meansthe gear segment is enabled to turn the dial pinion one space more thanthe position of the key lever permits the same to move.

The withdrawal of the locking latch of each higher registering device.is controlled by the next lower registering device and the withdrawalof each latch is effected when the next lower registering device hasmade one complete turn and arrived at zero. Each of the locking latchesis pivoted on the right hand side of its adjacent gear segment, so as toturn transversely with reference to the latter. The latch is turnedtoward the left into its operative position by a spring 51 (Fig. 10) themovement in this direction being limited by a shoulder 52 arranged onthe latch and bearing against the right hand side of the gear segment,as shown in Figure 10. 53 is an upright trip plate connected wit thelower end of each latch and arranged upper end extends toward the leftand normally at right angles or nearly so to the adjacent gear segment,when the latch is in its operatin position. 54 represents a number ofupright trip arms, each of whichis controlled by a lower registeringdevice and which turns the locking latch of the next higher registeringdevice into an inoperative position. This arm is mounted loosely withits lower end on the supporting bar 35 and is provided at its upper endwith a rearwardly and forwardly projecting hook 55, and in front andbelow said'hookwith a bend forming a bearing finger 56. 57 representstrip cams arranged on the left-hand side of each registering dialpinionand connected with the adjacent pinion and dial, but separated from thepinion by an intervening space or groove. The face of each of these camsbegins at its lowermost point near the axis thereof and then extendsoutwardly in a spiral line terminating with its highest point radiall inline with its lowermost point with whic 1 it connects abruptly. The tripcam of the fractional registering device has its face divided into eightarts, each part of which is arranged one-eig th of a s ace further fromthe center of the cam than t e preceding part, while the trip cams'ofthe higher registering devices each has its face divided into ten parts,each part being arranged one-tenth of a space farther from the axis ofthe cam than the preceding part. Each of the trip arms 54 extendsupwardly along the righthand side of the trip cam of a lower registeringdevice and its shoulder 56 engages with the face of this cam, while thehook 55 at its is adapted to engage with the trip plate 53 of the nexthigher registering mechanism. In the initial position of each trip arm,its shoulder 56 engages with the lowest part of its trip cam, asrepresented in Figures 2 and 9. As the trip cam is turned in thedirection of the arrow, Figure 2, at the same time that its dial andgearpinion are moved forwardly by the adjacent gear segment during theadding operation, the trip arm is moved backwardly by the graduallyrising face of the trip cam. During this backward movement of the triparm, its hook engages with the trip plate 53 of the next hi 'herregistering device and is deflected toward the right thereby, the hookbeing sutficiently elastic for this purpose. After the hook has passedin rear of said trip plate, the hook owing to its resilience springsback to itsnormal position, so as to stand behind said trip plate. Whenthe shoulder of the trip arm reaches the highestpart of the face on thetrip cam the trip arm has been shifted to its rearmost position. Uponnow turning this cam forwardly another space together with its companiondial and pinion, the highest part of the cam is carried from underneaththe shoulder of 5 the trip arm and the latter is moved forwardly overthe abrupt face of the cam until its shoulder 56 again engages with thelowest part of the cam face. Durin this movement of the trip arm, itshook stri es the rear side of the trip plate 53 of the next higherregistering mechanism and turns the same forwardly, as shown in Figure30, thereby disengaging the locking latch from the adjacent controllingarm and permitting the gear segment carrying the trip plate to moveforward one space. The forward movement of the trip arm is effected whenthe dial with which its trip cam is connected has made one completerotation and again stands at zero, whereby the addition represented bythis complete rotation is carried to the next higher registering device.The forward movement of the trip arm is effected quickly by aspring 58,which connects with a stationary cross bar 59 arranged in front of thetrip arms. The trip plate 53 of each registering device is so arrangedand is of such length that the hook of the next lower trip arm canengage with the rear side of the plate, for disengaging its latch in anyposition of the gear segment carrying the plate. If a gear segment islocked in its highest position by reason of none of its companion keyshaving been depressed, the withdrawal of its latch from the controllingarm simply permits the gear segment to drop one space and turn itscompanion dial pinion forward one space, while in engagement therewith,the movement of this d1 al representing one number carried up from thenext lower dial. If any one of the keys of the key levers has beendepressed, so

as to release the gear segment and permit the same to move downwardlyfor effecting an addition, and if during this time the next lowerregistering device has made a complete turn, so as to require thecarrying up of a number'from the next lower registering mechani'sm, thelatch of the higher registering device will be withdrawn while the sameis efi'ecting its addition, thereby causing the segment to descend andturn its dial one space in addition to the spaces corresponding to thelcpression of its respective key.

When the locking latch has been withdrawn so as to permit a gear segmentto, move downwardly one space farther than its controlling arm, thelatch remains in this position during the subsequent upward movement ofthe arm and the segment until the upward movement of the arm is arrestedby striking the stop bar 32 and the gear segment continues its upwardmovement independent of the arm the extent of one space. The gearsegment has now reached its highest position and its latch is againswung automatically by its spring over the controlling arm. Thecontrolling arm and gear segment now remain in this relative positionuntil another number is to be carried up from the next lower registeringde- Vice.

When the controlling arm has been retract-- ed to its highest position,the adjacent key lever is moved into its normal retracted position, sothat its locking shoulder 38 engages with the locking lug 33 of thecontrolling arm and locks the latter against downward movement. Thereturn movement of such key lever is preferably effected by a spring 60which connects the upper arm of the key lever with the transverse shaft9, as shown in F igures 2 and 7, or some other convenient part of themachine. The lower guide lug 46 on the gear segment compels the arm torise with the gear segment and avoids displacement of these parts withreference toeach other, and also serves as a stop to limit the upwardmovement of the gear segment.

The gear pinion and the co-operating gear segment of the fractionalregistering device are so constructed that the fractional dial makes onerotation whenever it is moved forward eight spaces. After the fractionaldial has made one rotation the whole number represented by this rotationis transferred by the first carrying device from the registeringmechanism of the fractional dials to the next higher registering devicewhich represents cents. The complete turns of each of the followingregistering devices are in like manner carried or transferred to thenext higher dial by the respective carrying device. The dial whichrecords the highest number, in this instance the millions, is preferablyoperated only by the adjacent carrying device of the next lower dial andis incapable of being operated directly from the key-board because it isnot provided with a key operating mecha nism. The mechanism whereby thedials 2 are all turned back to zero or the place of beginning after theaddition of numbers has been completed is constructed as follows:

61 (Figs. 2 and 7) represents a series of feeling rock levers which areadapted to shift the key levers, so as to permit the gear segments todescend the proper distance for resetting or restoring the mainregistering dals to zero. One of these shifting levers is mountedloosely on the supporting bar 35 adjacent to the left hand side of eachof the key levers and is provided on its upper arm with a forwardlyprojecting feeling finger 62 and with a shifting finger 63 which extendsbehind the upper arm of the adjacent key lever. The feeling levers havethe r fingers normally arranged in rear of the cams 57 and each of theselevers is turned so that its upper arm moves backwardly by the upper armof the adjacent key lever engaging with the shifting finger 6'3 of thefeeling lever. 64 represents a transverse pull bar arranged in rear ofthe lower arms of the feeling levers and connected with each of thelatter by a pull spring 65, as represented in Figures 2, 7 and 19. Thispull bar is connected at its ends to the lower end of two depending pullor rock arms 66, which are secured at their upper ends to the rock shaft9, as shown in Figure 19. Upon turning this rock-shaft, so as to swingits depending pull arms backwardly the feeling levers are turned bymeans of the springs 65 so as to move the upper arms of these leversforwardly. This movement of the rock-shaft 9 is effected by a cam 67(Figs. 14, 21 and 35), which is mounted on the left-hand side of therocking frame 29 and which is constructed substantially the same as thecam 14 which is mounted on the rocking frame 15. As shown in Figures 14and 21, this cam is pivoted at its rear end by a transverse pin to therear portion of the rocking frame 29 and is provided at its front endwith an incline or cam face 69-, and in rear of the incline with aconcentric face 68. The cam 67 can be raised and lowered with its frontend into an inoperative or operative position, this movement beinglimited by means of a lug 70 arranged on the cam as shown in Figure 19,and projecting into a slot 71 in the adjacent rocking frame in the samemanner in which the movement of the cam 14 is limited, as shown inFigure 36.

72, Figures 14 and 19, represents a rearwardly projecting rock-armsecured to the rock shaft 9 and provided at its rear end with a rolleror projection 73 which is adapted to be engaged by the cam 67 forturning the rock shaft 9. When numbers are being added with the machine,the cam 14 is depressed, as shown in full lines, Figure 2, so as to bein a position when moved forwardly by the rocking frame 15 to engage theroller on the arm 13, for moving the gear segments into engagement withthe dial pinions, and during this time the cam 67 is lifted into theposition shown in full lines, Figure 14, so that when the rocking frame29 is moved forwardly, the cam 67 will clear the roller 73 of the rockarm 72 and not disturb the roellr1 shaft 9 and the parts connectedtherewit If it is desired to restore all of the dials 2 to zero, the cam14 is raised into its inoperative position, shown by dotted lines 14 inFigure 2, and the cam 67 is lowered into its operative position, asshown by dotted lines 67* in Figure 14. Upon now turning the rock-shaft20 by hand so as to move both rocking frames 15 and 29 forwardly, thecam 14 passes over the roller 18 of the arm 13 without disturbing theSame, but the inclined front of the cam 67 engages with the roller 73 onthe rear end of the rock-arm 72 and raises the same until this rollerengages with the concentric part 69 of this cam. By this movement of thearm 72, the rock shaft 9 is turned in the direction for moving itsdepending arms 66 rearwardly and pulling the springs 65 rearwardly. Thispull on the springs 65 er parts of the trip cam are iguana causes thefeeling levers to be turned until the feeling fingers of their upperarms engafge with the spiral surfaces of the trip cams. A er the feelingfingersbear against these cams, their movement is arrested and thecontinued backward movement of the pull bar 64 simply stretches thesprings 65 until the bar reaches the end of its backward movement. Thefeeling finger of each feeling lever engages with that part of thesurface of the ad acent trip cam which is directly opposite the feelingfinger, and as these trip cams are turned with the adjacent dials theypresent different parts of their spiral surfaces to the opposing feelingfingers, which causes the forward movement of the upper arms of thefeeling levers to be arrested in different positions when swung,forwardly. During the forward movement of the upper arm of each feelinglever, its shifting finger 63 engages with the rear side of the upwardlyprojecting arm of the adjacent key lever and moves this arm forwardly.The construction of the parts is such that the spiral surfaces of thetrip cam bears a definite relation to the step-shaped series of stopshoulders on the upper arm of the key lever. When the feeling finger ofthe feeling lever, upon being moved forwardly, bears against the lowestpart of the adjacent trip cam, the adjacent key lever is carriedsimultaneously forward with the feeling lever the greatest distance andits uppermost stop shoulder is carried into the path of the stop lug ofthe controlling arm. The succeeding parts of the spiralsurface of thetrip cam are so constructed that they rise progressively higher andarrest the forward movement of the feeling lever when the same hascarried the adjacent key lever with its corresponding stop shoulder intothe path of the stop lug of the controlling arm. This forward movementof the feeling lever and that of the upper arm of the key lever isgradually reduced as the progressively highpresented to the feelingfinger, and when the highest part of the trip cam is presented to thefeeling finger, the feeling lever is prevented from moving forward atall and the upper arm of the key lever is not moved with its lockingshoulder out of engagement with the locking stop of the controlling armand consequently the companion gear segment connected therewith is heldagainst downward movement. After the rocking frames 15 and 29 have beenturned forwardly sufiiciently to engage the several feeling fingers ofthe feeling levers with their respective trip cams, the rear ends of thesegmental notches 28 in the rocking frames engage with the cross bar 25and depress the same, thereby moving the lifting bar 22 downwardly andat the same time ulling down the springs 27. This downward pull on thesesprings causes 65 each spring to pull'its respective gear segment downas far as possible, and after the downward movement of the segment hasbeen arrested the continued downward movement of the cross bar 22together with the rocking frames simply stretches these springs untilthe bar reaches the end of its downward movement. If a gear segment islocked in its uppermost or zero position its spring 27 will be stretchedits fullest extent, whereas, if a gear segment moves downwardly more or'less before it is arrested by its shifted key lever, its spring 27 willbe stretched less in proportion. This downward movement of the gearsegments, which are free to move in this direction takes place while thegear segments are in their retracted position and out of engagement fromthe dial pinions, 'so that the dials are not affected by this movementof the segments. After the rocking frames have reached the end of theirforward movement and the roller 73 has dropped off from the rear end ofthe concentric portion 69 of the cam 67, the gear segments are movedforwardly by hand operated mechanism into engagementwith theirrespective dial pinions and are held in this position during the en--tire subsequent backward movement of the rocking frames, which iseffected by hand operated mechanism. During the backward movement of therocking frames, the gear segments are raised to their highest positions,

while in engagement with the dial pinions by the rod 22 and connectingparts and turn the dials backwardly. At the end of the upward movementof the gear segments the latter are released, so as to permit them tomove into their retracted position, out of engage.- ment from the dialpinions.

During this operation, those gear segments which are held or locked intheir highest positions, by reason of their dials being at zero, aresimply moved forward at the end of the forward movement of the rockingframes, so as to engage with their respective dial pinions and are againmoved backwardly out of engagement therefrom at the end of the backwardmovement of the rocking frames, without disturbing their respectivedials. Each of the unlocked gear segments is moved downwardly a numberof spaces correspondingto the number which its dial backward the samenumber of spaces that the gear segment was depressed. Inasmuch as eachgear segment was permitted
